Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed May 2, 1910. Serial No. 558,832.

To all whom it may concern:

Be it known that we, ROYAL J. SCQVILL and WILLIAM E. BROWN, citizens of the United States, residing at Glens Falls, in the county of lVarren, State of New York, have invented anew and useful Paper-Machine, of which the following is a specification.

This invention relates generally to paper machines and particularly to an adjustable sheet formation rack which is to be mounted in the sluice or flow of the paper machine.

The present invention is in the nature of an improvement on the subject matter of our application for improvements in paper machine racks, Serial No. 509,621, filed July 26, 1909, and allowed January 13, 1910.

One of the objects of the present invention is to provide means for readily adjusting the blades of the rack away from or toward the blades of the sluice.

A further object of the invention is to provide means for securing either a vertical or lateral adjustment of the rack members.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming partof this specification :F igure 1 is a side elevation of the sluice, the rack, and the brackets for adjustably connecting the rack with the sluice. Fig. 2 is a view in elevation taken at a right angle to Fig. 1. Fig. 3 is a plan view of the construction shown in Figs. 1 and 2. Fig. 1 is a detail view of the follower block used between the parallel arms of the brackets shown in Figs. 1, 2 and 8. Fig. is a detail view of the adjustable box in which the sections of the rack are adjustable. Fig. 6 is a plan View of Fig. 7 is a view similar to Fig. 5 illustrating a modified construction of rack mounted in the adjustable box. Fig. 8 is a view taken at a right angle to Fig. 7, showing the construction of rack which is used therein.

Like reference numerals indicate corresponding parts on the different figures of the drawing.

The improvements of the present invention are particularly intended for use in connection with a paper machine of the Fourdrinier type.

The reference numeral 1 indicates the sluice which extends transversely across the How of the paper machine. The sluice 1 may be of any suitable form and construction. Connected with the upper end 2 of the sluice 1 is a bracket 8 having a pair of depending arms 4 and 5. The arm 4, preferably is longer than the arm 5 to engage the rear surface of the blades 1. Extending through the arms 5 is a set screw 6 which is intended to engage under the overhanging portion 2 at the upper end of the sluice. The screw 6 can be locked in position to hold the brackets 3 on the sluice, by means such as the check-nut- 7. The bracket 3, as shown best in Fig. 3, is provided at its upper end with two parallel extensions or arms 8-8 between which is slidably mounted a follower block 9 shown best in Fig. 41 of the drawings. The follower block 9 is formed in its sides with grooves 10 which embrace the extensions 8 so as to cause the follower to be slidable thereon. The follower 9 is also provided with an arm. 11 through which extends a threaded rod 12 which is threaded through the upper end of the bracket 3 and is provided with a knurled head 13. The threaded rod 12 is provided between the arm 11 and the follower 9 with a head 1 1 which causes the rod 12 to have a swiveled connection with the follower 9. By rotating the threaded rod 12 by means of the head 13, the follower 9 can be adjusted longitudinally between the extensions or arms 8 so as to regulate the space between the rack, hereinafter described, and the sluice.

Extending vertically through the follower. 9 is a threaded rod 15. The threaded hanger extends loosely through the follower 9 and capable of vertical adjustment therein by means of the buttons 16 and 17 which are threaded on the rod 15 and bear against the upper portion of the follower 9. The button 17 is used to lock the button 16 in any position to which it has been adjusted upon the rod 15. Connected with the lower end of the threaded hanger 15 is a box 18. The box 18 is formed with a transverse passage with which communicates a slot 19. Extending through the slot 19 is one of two members 20 which constitute the rack, said .members being adjustable longitudinally with respect to each other. Each of the rack members 20 is provided at its upper end with an overhang 21 located within the box 18 so as to prevent the rack from dropping downward out of the box.

The overhanging portions 21 at the upper ends of the racks 20, as shown in Figs. 5 and 6, may be disposed on opposite sides of the rack members 20. For the purpose of holding the overlapping ends of the rack members 20 in the position to which they have been adjusted, a set screw 22 is provided in the block 18 in Fig. 5 to engage the rack members 20- below the overhanging portions 21 thereof. It is to be understood, that the rack members 20 only overlap each other adjacent the centers of the flow. For this reason the box 18 of the hanger 15 in Fig. 5 is constructed so as to receive the overlapping middle portion of the rack members, and the box 18 shown in Fig. l is intended to engage one of the rack members 20 adjacent the outer end thereof.

If it be desired to dispense with the double hanger 18 shown in Fig. 5 for supporting the overlapped middle portion of the rack members 20, the rack members are formed as shown in Figs. 7 and 8. That is to say one of the members 20 is formed with an overhanging portion 21 which is mounted on a higher plane than the overhanging portions 21 of the other rack member 20. Moreover each of the rack members is provided with a longitudinal slot 30 and a bolt 31 provided with a button The bolt 31 of each of the rack members 20 projects through the slot 30 of theother rack member and has the button 32 mounted thereon, sotliat when the two buttons 32 are tightened up the two rack members are locked together to prevent any further longitudinal adjustment of said rack members upon each other. By reason of the fact that the two overhanging portions 21 of :the two rack members lit against each other, it will be obvious that a strong rigid structure is produced and that the action of said structure is to prevent any sagging of the rack members adjacent. the center of the sluice.

By using the construction shown in Figs. 7 and 8 the necessity of employing hangers adjacent the center of the sluice is amided.

It will be obvious that the construction shown herein permits the rack to be longitudinally adjusted so as to fit sluices of different widths and that the rack members can not only be adjusted vertically to regulate the distance which they shall project into the stock, but they can also be adjusted longitudinally away from or toward the sluice.

The improvements of the present invention are strong, simple, durable and inex pensive in construction as well as thoroughly practical and eflicient in use. Moreover they can be readily applied to paper machines which are already in use.

It is to be understood that our rack can be made with any number of teeth from one up, and that the teeth may be of any desired shape and form.
